Dn 0 T. N E U- mfm l gases through regenerative furnaces, or in anyother connection. The valve and valve seat may be made withoutwater-cooling passages as in many cases iron or castingsnfill.suiiiciently resist the heat, the weight of the valve holding'itclosed and causing it to tit against the seat. I Many changes may bemade in the form of valve, its seat, and the operating mechanism Withoutdeparting from my invention. 'claim: l. The combination of an inclinedvalve seat arranged transversely of a conduit, a valve adapted to 'seatby ,gravity in an inclined position on said seat, and actuatingconnections for the valve, said connections having means whereby th'evalve is drawn backwardly against the seat during a portion oi itslifting movement and is then lifted in a substantially verticaldirection orthe remainder of its movement; substantiaily as described. y

' 2. The combination with an inclined valve f seat arranged transverselyof a conduit, of a valve of the gate type arranged to rest by gravity inan inclined position on said seat, and an actuating connection for saidvalve, said actuating connection having :i flexible member whose pointof support is slightly to one side of the center of gravity of thevalve, whereby said valve is drawn backvvardly aga-inst its seat duringa portion oil its liftingy movement, and istlien raised'ina'osubstantially vertical direction during the remainder ot itsmovement; substantially as l described.

3. The combination with a valve-seating member having an inclinedseating face, of hollow water-cooled valve arranged to rest in aninclined position against said face, spaced water-circnlating pipesconnected eX- teriorly to the upper and lower portions of said valve andcommunicating with the interior thereof, andn actuating means connectedto said pipes, substantially as .described.'

4. The combination' with an inclined valve sert, ci' a hollowwater-cooled valve arranged to rest in an inclined positionv againstsaid seat, havinglwater circulating pipes rigidly connected to the upperand lower portions of said valve, together with actuating means attachedto said pipes, said actuating means being arranged to cause the valve toLi-51ans swing backwardly by gravity against said seat during at least aportion of its raising movement; substantially as described.

rlhe combination with a hot-blast conduit pipe having a transverseopening, an inclined water-cooled seat surrounding said opening, ahollow water-cooled valve adapted to rest by gravity in an inclinedposition against the inclined surface of the seat,

casing above the valve and communicating with the conduit, a slottedcover for said` casing,.lifting members" attached to the valve andextending upwardly through the casing and through said slots, and meansfor clos#` ing the slots around said. liiting members;

members for the said slots to permit thefnec-` essary movement ofsaidlifting members in the slots; substantially as described.

7. The combination with an inclined valve seating member, pf a valvearranged to restv in an inclined position against an inclined seatingface of said member, and lifting means for said valve, said liftingmeans and 'valve being arrangedto move laterally to` ward.- and awayfrom the inclined seating` face of said seat as tlievalve is raised andlowered; substantially as described.

8.` water-cooled hot blast valve of the gate type, adapted to rest in aninclined position against its seat, the casing having a slotted coverplate, water pipes extending to the valve through slots in the coverplate, means iorclosing said slots, and a connecF tion arranged to liftthe pipes and move them sidewise: substantially as described.

ln testimony whereofl have hereunto `set my hand.
